What I do if I can't sleep,
1) don't force myself to sleep but I do stay in bed & read then when my eyes get, tired I fall asleep
2) listen to quiet music, this really helped put my kids to sleep
Like.... rockin, rollin, ridin, out across the bay, all is bound for morning town many miles away... don't know composer. I think it's an ethnic lullaby.

3) or to put my kids to sleep, I'd play the guitar for them or I'd tell them a quiet story(I made up a character and a family and told the story of this family) with a majical twist.

It's great to be able to get into character in such a way as to convince even in a picture.
